Apple Inc.’s (NASDAQ:AAPL) upcoming Mac operating system update, called the OS X 10.9.3 Mavericks, is expected to be released soon, as the company has seeded the ninth beta version of the upcoming update to its registered developers. The latest beta comes only a week after Apple rolled out the eighth beta of OS X 10.9.3 Mavericks.

The new beta build is currently available to developers via an update in the Mac App Store or as a download on Apple’s online developer center.

The previous betas of the new OS X Mavericks 10.9.3 update included support for scaling the double pixels for 4K monitor output, suggesting a new native “Retina” resolution option for late-2013 MacBook Pro with Retina display, AppleInsider reported.

In addition to the new OS X beta, Apple also released Safari 7.0.4 Seed 1, which included minor modifications to OS X compatibility.

The ninth beta of the OS X 10.9.3 Mavericks labeled 13D61 came after Apple reportedly distributed a new OS X 10.9.3 build 13D62 to AppleCare employees, indicating that the final release of the software is imminent.

According to 9to5Mac, which first reported about the build 13D62, the new OS X 10.9.3 Mavericks could be released as soon as this week. The report also said that Apple has already started working on OS X 10.9.4.

Apple recently introduced a new “OS X Beta Seed Program,” which allowed all Mac users to sign up for and test OS X betas before the final version is released to the public. However, the latest beta build does not appear to be included in the new program.

In addition to the new Retina resolution option for 4K displays, the next OS X update is also expected to enable users to sync contacts and calendar info locally.
